3.2 Chain
3.2.1
The quantity and location of the chain components including cushion rubbers, chain springs and striker
plates depend on the hoist model, capacity and limits switches. Never operate the hoist with incorrect,
missing or damaged chain components. Refer to the hoist's nameplate,
Table 3-2
, and
Figures 3-2, 3-
3, and 3-4
and ensure that all chain components are in the correct location and properly installed.
3.2.2
When the hoist is used without a chain container, the free end of the chain is attached to the hoist body
as shown in
Figure 3-4
. Connect the no load end of the chain to Chain Guide A with the End Wire or
End Suspender
provided. For 5 ton hoist, connect the no load end of the chain directly to Chain Guide
A if Chain Guide A is notched to accept the chain. Make sure the chain remains free of twists and the
chain Stopper is installed on the correct link. Refer to
Table 3-2
for proper placement of Stopper.
